Abstract

La présente invention concerne un procédé de réalisation d'une pile solaire à partir d'un substrat de silicium (1) dopé p ou dopé n qui présente une première surface principale (2) qui, en cours d'utilisation, sert de côté d'incidence lumineuse, et une deuxième surface principale (3) qui sert de côté arrière. Selon l'invention, le procédé comprend les étapes suivantes : application d'une couche mince (7) qui comprend principalement de l'aluminium, sur la deuxième surface principale (3); application et séchage d'une pâte vitrifiante diélectrique (11) sur la deuxième couche principale (2) pour recouvrir la couche mince d'aluminium (7); chauffage et/ou frittage de la pâte (11) sur la deuxième surface principale (3), notamment à des températures supérieures à environ 577°C, pour produire une couche dopée en aluminium (8) dans la deuxième surface principale (3); et élimination de la couche vitrifiée (12) formée lors du chauffage et/ou frittage, et d'une couche eutectique aluminium-silicium formée lors du chauffage et/ou frittage, de la deuxième couche principale (3), ce qui permet d'exposer la couche dopée en aluminium (8).
